I do he're'by dec-lare that `the following is. a full and exact descriptionthereofpreference being had to the The object of` this invention is inthe nature-of an` improvementin jinopheads, wherebygreat economy e of a skeletonscrew, andirin this, way preservingall the' y i essential featnresof the best mop-headsheretof'ore f constructed,'but `in a far cheaper, simpler, and eica" Figure 1 represents aifeweviewof my niop-head` The Schedule referred .to ln these Letters Patent partei' 'the unxne` around which it so revolves is of sornewhat less'damef ter' than thel other part of the handle, thusenabling it to enter the socketd, where it is xedby' the rivet e,

able size, is bent-inthe shape shown in iig. 1,- its vertical sidespassing into and working freely throughI Ir'ecesses g in the ends ofthe' cross-head, and the vends of said binder beingbent or formed with shoulders s insuch manner as will admit of their passing between the threads a'oi' the screw C, in the mannershown in iig. l; and .the ends b are bent at 'right angles tothe" shoulders s, 'and pass'under thevscrew-thread a, and

enter into the grooves or guides c in the handle E, so

that, when the screw O is revolved, the edges of the screwthreads a, will press against said shoulders s and force said binder-'np or down, according to the 'way said screw may be revolved, either right or left, the ends b oi' said binder being conued and guided in their action by working in the guidesorgrooves c, andthe mop-cloth being clamped between the binderV and 4the c1oss-head, as the binder may be moved up or down,-as hereinbefore described.

Having thus descn'bedmy invention,

What I- claim as new, anddesire to secure by 1. A mophead, wherein'the binder is operated by means of a tubular screw, said vscrew being-formed oi' skeleton or open screw-threads, in the'mannerand for the purposcsherein described. y e 2. A mop-head, wherein the ends of the binder pass between the'open threads of-a screw and .work up and down in grooves or guides formed in the handle, 1n the mauner andfor thepurposes hereindescribed.
